摘　　要：使用ＴＰＲ和Ｈ２－ＴＰＤ技术对镍铝系催化剂的还原和氢脱附性能进行了研究，并与其催化性能相关联．结果发现，镍铝系催化剂的氢脱附能力与其催化性能之间有一定联系，脱附氢能力越强，催化剂的甲烷部分氧化反应性能就越好．但催化性能与还原性能无直接关联．H 2 TPR(Temperature Programmed Reduction) and H 2 TPD (Temperature Programmed Desorption) techniques have been used to characterize the reduction and hydrogen desorption properties of M Al and Ni M Al catalysts. The results show that the catalytic activity of NiO MO x Al 2O 3 catalysts increased with the increase of the ability of H 2 desorption. For Ni/Al 2O 3 catalyst, there is no correlation between the catalytic activity and the reduction property.
